Can't get data-title, just data-slug - php

Question

HTML
<article class="movie-summary" data-slug="slug-goes-here" data-title="This is a Title">
...
...
</article>
PHP
$html = file_get_html( 'example.com' );
foreach( $html->find('article') as $data) {
$property = 'data-title';
echo $data->$property;
}
Hey all, so I want to be able to get all data-title from all articles off a particular site. When I use data-slug I get data back yet when I use data-title I get nothing, with the help of this post

Answer 1

If you look at the actual HTML code you are trying to parse (the link provided at comments), you see that it is not valid:
<article class="movie-summary hero" data-slug="aiyaary-hindi"data-title="Aiyaary">
...
</article>
Meaning, there is no space between data-slug and data-title attributes. So to fix this I suggest to add necessary spaces. Like so:
function placeNeccessarySpaces($contents) {
return preg_replace('/"data-title/', '" data-title', $contents);
}
This is similar to this answer. Then:
$contents = placeNeccessarySpaces(file_get_contents('http://example.com'));
$html = str_get_html($contents);
foreach( $html->find('article') as $data) {
$property = 'data-title';
echo $data->$property;
}

This is simply working fine, Verified result
<?php
include 'simple_html_dom.php';

foreach( $html->find('article') as $data) {
